LIFT FOR FLUSH-VALVES.

Application filed February 3, 1920.

To all whom it may concern:

Be it known that I, MILTON C. RENO, a citizen of the United States, residing at Corliss, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lifts for Flush- Valves, of which the following is a specification.

This invention relates to new and useful improvements in flushing devices for water closet tanks, and more particularly to the lift mechanism for actuating the flush valve to permit the flushing action to take place by discharging the water from said tank.

The primary object of the invention is to provide a device of the character stated, in a manner as hereinafter set forth, which is weight controlled and operated and which will automatically assure the dropping of the lift lever after the flushing operation, thereby permitting the closing of the flush valve which is often rendered inoperable by the improper functioning of the lift mechanism.

Further objects of the invention are to provide a device of the class described, which is simple in its construction and arrangement, strong, durable and efficient in its use, readily installed, and inexpensive to manufacture.

To the accomplishment of these and such other objects as may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawing wherein is shown an embodiment of the invention, but it is to be understood that the device shown is merely illustrative and that various changes in the form, proportion and minor details of construction may be resorted to, without departing from the principle or sacrificing any of the advantages of the invention, which come within the scope of the claims hereunto appended.

In the drawing forming a portion of this specification and wherein like numerals of reference designate corresponding parts throughout the several views:

Figure 1 is a side elevation of the lift mechanism for flush valves in accordance with this invention.

Fig. 2 is a top plan view thereof with portions shown in section and with portions broken away.

Specification of Letters Patent.

Patented Oct. 25, 1921 Serial No. 355,911..

Fig. 3 is an inverted side view of the device with portions broken away.

Fig. i is a similar view of a modified form.

Referring in detail to the drawing there is shown a lift mechanism for flush valves adapted to be attached to the side of a watercloset flush tank 1. The device comprises a sleeve 2 having its forward end threaded exteriorily, as at 3. Adjacent the rear end of the sleeve 2 is an integrally formed shoulder 4 which is provided with a squared forwardly projecting outer face 5. The sleeve 2 is mounted in the aperture 6 in the side wall of the flush tank 1, and to prevent the turning of the sleeve 2 in the aperture 6, the inner portion of the latter is formed with a squared recess 7 in which the squared forwardly projecting outer face 5 on the shoulder 4. is adapted to seat. Thesleeve 2 is secured in the side wall of the tank 1 by means of the nut 8, which engages the threaded forward end of the said sleeve, in connection with the shoulder t-which abuts against the inner face of the tank 1 when the nut 8 is tightened.

The sleeve 2 is further provided with a rearwardly inclined angularly disposed bracket 9 which is formed integral with the shoulder 4. Fixed to the outer end of the bracket 9, and extending rearwardly and at right angles with respect thereto, is the lift lever shaft 10.

A lift lever 11 is tiltably mounted on the shaft 10, and is prevented from moving laterally thereon by the pins 12, one of which is positioned on either side of the bearing hub 18, of the tilt lever 11, and fixed in the shaft 10. The outer end of the tilt lever 11 is provided with a series of apertures 14: in any of which the operating rod 15 may be pivotally and adjustably connected. The lower end of the operating rod 15 is adapted to connect with the flush valve, and the vertical movement of the former adapted to actuate the flush valve.

Rotatably mounted in the sleeve 2 is the operating shaft 16, the forward end of which carries the operating handle 17 threadably connected thereto, as at 18, or fixed thereto in any other suitable manner. Fixed to the rear end of the operating shaft 16, by means of the nut 19, is the disk 20. Securely mounted in the disk 20, adjacent its periphery, is a rearwardly extending actuating pin 21, the rear end of which is adapted to engage the recessed portion 22, of the lift lever 11, and tilt the latter to vertically lift the operating rod 15 to actuate the flush valve. To prevent the shaft 16 from shifting longitudinally in the sleeve 2, a transversely extending pin 23 through the shaft, abuts against the rear end of the sleeve 2.

The handle 17 is designed to be made from heavy material or to be weighted so that the same will normally dispose itself in the pending position unless actuated to operate the flush valve. The actuating pin 21 is so positioned on the disk QO'Wlth respect to the handle 17, that when the latter is in the depending, downward, or inoperative position the former willbe at the ex.- treme upward position, and vice versa.

The shafts l0 and 16 are preferably positioned in parallel horizontal alinement with respect to each other, and the recess 22 in the lifting lever 11 provided to give proper tilting movement to the latter. 1

In the modified form shown in Fig. 4, of the drawing, instead of using the disk 20 on the rear end of the shaft, an arm 24 is used for carrying the actuating pin, which latter in the modified form is provided with a roller 25. Otherwisethe construction and operation of the modified form is identical to the preferred form thereof.

lVhen operating the flush valve in a water ing a sleeve adapted to be extended through v the wall of a flushing tank and provided on its inner end with a shoulder and its outer portion with peripheral threads and a squared portion between the threads and the shoulder, a shaft extending through the V sleeve, a nut on the shaft, a nut lnclosing the threaded portion, of the sleeve and co-actinn with the nut on the shaft to secure the sleeve to the wall, a pin carrying member on the inner end of the shaft, an elongated pin extended from said member, a bracket'inte-V ral with said shoulder and extended inwardly, a shaft secured to the bracket, a lift lever extending intthe same plane throughout and pivoted on the shaft secured to the bracket and having its top edge depressed to provide a recess in which said pin operates to tilt the lever and a wei 'hted handle on 7 h the outer end of said shaft. 7 V

In testimony whereof I afiix my signature.
